I have an 06 LBZ 2WD crew cab with a diablo programmer on the 85HP tune and 37/13.50/17 Toyo Muds and an 8" lift. What do i have to do to rid of the abs/parkin brake lights from coming on and the service brake system. Ive been trying to play with the numbers on the tune for awhile now and nothing seems to work. Somebody said that the abs isnt recognizing the change and i have to do something different to make it see the change in tire size.

Where do i find these items?
A Tech II? Any GM dealership service department would have one. Otherwise they're pretty rare unless some individual just decided to purchase one for themself.
